He aha ka HSS?

ʻO ke kila kiʻekiʻe (HSS) ka mea maʻamau no nā mea ʻoki metala mai ka makahiki 1830.

ʻO ke kila māmā kiʻekiʻe (HSS) he kila mea hana me ka paʻakikī kiʻekiʻe, ke kūpaʻa ʻaʻahu kiʻekiʻe, a me ke kūpaʻa wela kiʻekiʻe. Kapa ʻia ʻo ia he kila ʻoi, ʻo ia hoʻi, hiki iā ia ke paʻakikī a hoʻomau i ka ʻoi ʻoiai ke hoʻomālili ʻia i ka lewa i ka wā e kinai ana.

Loaʻa i ke kila kiʻekiʻe ka hapa nui o ke kalapona a me nā metala ʻē aʻe. Ke noʻonoʻo nei ʻo ka haku mele ʻana ka hiʻohiʻona koʻikoʻi o ke kila kiʻekiʻe, aia ka HSS i ka tungsten, molybdenum, chromium, vanadium, cobalt, a me nā mea hana carbide ʻē aʻe i ka huina o 10 a 25% o nā mea hoʻohui. Hāʻawi kēia mau haku mele i ka HSS me ka ʻoki maʻamau a me nā waiwai mechanical e like me ke kūpaʻa ʻaʻahu. I ka moku'āina pio, hao, chromium, s    ome tungsten, a me ka nui kalapona i loko o kiʻekiʻe-wikiwiki kiʻekiʻe hana carbide paʻakikī loa e hiki ke hoʻoikaika i ke kapa kila.

Eia kekahi, ʻike ʻia ka HSS i ka paʻakikī wela kiʻekiʻe. ʻO kēia no ka mea ua hoʻoheheʻe ʻia ka tungsten i ka matrix. ʻO ka paʻakikī wela o ke kila kiʻekiʻe hiki ke piʻi i 650 degere. ʻO Tungsten, molybdenum, chromium, vanadium, cobalt, a me nā carbide ʻē aʻe he mau mea e kōkua ai i ka mālama ʻana i ka paʻakikī kiʻekiʻe ma ka ʻoki ʻana i ka wela kiʻekiʻe (ma kahi o 500°C).

ʻO ka hoʻohālikelike ʻana i ka HSS me nā kila mea hana kalapona hiki ke ʻike i ka mea i ʻoi aku ka ʻoi aku ka paʻakikī ma ka lumi wela ma hope o ke kinai ʻia ʻana a me ka huhū ʻana i nā wela haʻahaʻa. Akā inā ʻoi aku ke kiʻekiʻe o ka mahana ma mua o 200 ° C, e hāʻule nui ka paʻakikī o ke kila mea hana kalapona. Eia kekahi, e hāʻule ka paʻakikī o nā kila mea hana kalapona ma 500 ° C i kahi pae like me kona kūlana annealed, ʻo ia hoʻi ua nalowale loa kona hiki ke ʻoki metala. Ke kaupalena nei kēia hanana i ka hoʻohana ʻana i nā kila mea hana kalapona i nā mea hana ʻoki. ʻO nā kila māmā kiʻekiʻe e hana i nā hemahema kī o nā kila mea hana kalapona ma muli o ko lākou paʻakikī wela maikaʻi.

ʻOi aku ka maikaʻi o ka carbide sima ma mua o ka HSS i ka nui o nā hihia. Inā makemake ʻoe i nā huahana tungsten carbide a makemake ʻoe i ka ʻike hou aku a me nā kikoʻī, hiki iā ʻoe ke CONTACT US ma ke kelepona a i ʻole ka leka uila ma ka hema a i ʻole SEND US MAIL ma lalo o ka ʻaoʻao. Ke kali nei mākou i kāu nīnau.
